"A comparison of three methods of predicting the risk of recurrence in women treated for estrogen-receptor (ER)-positive breast cancer finds that only the breast cancer index (BCI) \u2013 a biomarker based on the expression levels of seven tumor-specific genes \u2013 accurately identifies patients who continue to be at risk after five years of treatment with either tamoxifen or the aromatase inhibitor anastrozole. The study comparing the BCI with two other prognostic tests has been published online in Lancet Oncology."^^<http://www.w3.org/2001/XMLSchema#string>
